Two computer programs give the same 120,000 reference control counts for MR-ART v1.0.2.

An independently written integer score and binary-search program was compared with a prior floating-point analysis of the same MR-ART v1.0.2 tables and saved reference assignments. It matched all 120,000 control counts and all 12 raw or own-reference rows; none of 783 comparison checks failed, and the maximum absolute difference in compared numerical fields was 0.0. For entropy focus criterion (EFC), the own-reference mean agreement exceeded the maximum of 10,000 controls under each of two reference schemes, with zero exceedances in each scheme. The plus-one Monte Carlo values were 1/10001 before adjustment and 6/10001 after Holm adjustment. This is an arithmetic reproduction on fixed tables, not a new sample or a test of reference exchangeability, population uncertainty, causality, processing effects, or clinical thresholds. The work uses source files recorded as OpenNeuro ds004173 v1.0.2 and preserves their hashes and source URLs.
